var dateStr = "index?$hh#,$yy#,$gg#";

  var regx = /\$(.+)\#/;

  
   var d = text.match(regx);

   for (var i in d) {
       alert(i+":"+ d[i]);
   }

//上述代码 正则表达式 提取字符串里面 $(.)#这里面的字符串  当字符串里面只有一对字符的时候可以用( var dateStr = "index?$hh#";)  当有多对的时候就出问题......求大神帮忙改一个

  var dateStr = "index?$hh#,$yy#,$gg#";
var ar,d=new Array();
  var regx = /\$(.+?)\#/g;

  
   //var d = dateStr.match(regx);
while(ar=regx.exec(dateStr)){
      d.push(ar[1]);
}
   for (var i in d) {
       alert(i+":"+ d[i]);
   }

------解决方案--------------------
<script type="text/javascript">
 var dateStr = "index?$hh#,$yy#,$gg#";

 var regx = /\$.+?\#/g;

    
  var d = dateStr.match(regx);

  for (var i in d) {
      document.write(d[i]+"<br/>")
  }
</script>
这样试试
